## Feature Control Frame Reporting Tables

PC-DMIS provides you with a variety of reporting tables that can be output when you generate reports for your measurement routine. These report tables look different from how legacy dimensions appear in your report.

Legacy dimensions all appear in one table. Feature Control Frame (FCF) reporting tables, by contrast, are divided according to different sections of the FCF, which provides a cleaner-looking report. For example, you might have one table that shows the size portion of the FCF while another table shows the form information.

As a visual example, consider this legacy Position dimension in the Report window:

Sample Report of a Legacy Position Dimension as a Single Table

Now, contrast that with an FCF Position dimension in the Report window shown here:

Notice that the FCF Position is actually contained in distinct tables that display the following information:

- Size

- Position

- Datum Shift

- Summary

All of the other FCF dimensions also use a similar reporting style. While these reporting tables differ from the style used for legacy dimensions, they provide a cleaner, easier-to-read approach to reporting dimensioning information.

A Note on Datum Shift

PC-DMIS reports the Datum Shift table only when the datum reference frame is not fully constrained. In the above image, for instance, the secondary datum is at MMC, so the Shift X and Shift Y are unconstrained to the extent of the bonus on the secondary datum. (See the description of "Fit to Datums" in the "Nominals Tab" topic.)

When a datum reference frame is only partially constrained, those degrees of freedom that are constrained show the text "Fixed” instead of an actual value (even though internally, the value is zero). This makes it easier to differentiate between those degrees that are constrained and those that are free. When the datum reference frame is fully constrained, PC-DMIS does not report the Datum Shift table because all the values for Shift and Rotation would be zero.

The following example shows the same report as above but with the secondary datum at RFS. Notice that in this case there is no Datum Shift table in the report:
